Abstract The main objective of net pay determination, as an important step any reservoir study, is to exclude non-reservoir intervals so that better results are obtained from characterization, hydrocarbon in-place calculations, and dynamic flow simulation the reservoir. This study a comprehensive presentation most applicable methods available for highlighting their strengths, limitations, input...

Net pay thickness is defined as that portion of a reservoir which contains economically producible hydrocarbons with today’s technology, prices, and costs. This thickness is a key parameter of the volumetric calculation of in-place hydrocarbons, well test interpretation, and reservoir characterization. A reservoir interval is considered as net pay when it contains hydrocarbons that can flow at ...

A growth model for porous sedimentary rocks is proposed, using a simple computer simulation algorithm. We generate the structure by ballistic deposition of particles with a bimodal size distribution. Porosity and specific surface area are calculated varying the proportion of small and larger particles. Permeability and it’s variation with porosity are studied. The fractal nature of the pore spa...

Rock strength is an essential and effective property in the rock drilling, excavation, cost evaluation. This work aims to examine a practical approach evaluate geomechanical properties that control drillability, such as uniaxial compressive (UCS) by utilising some petrophysical parameters (porosity bulk density) elastic (Young’s modulus, slowness). To achieve this aim, study was conducted on Ju...

Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...

Characterisation of the pore space in carbonate reservoirs and aquifers is of utmost importance in a number of applications such as enhanced oil recovery, geological carbon storage and contaminant transport. We present a new experimental methodology that uses high-salinity contrast brine and differential imaging acquired by X-ray tomography to non-invasively obtain three-dimensional spatially r...

Initializations of the petrophysical parameters significantly affect results reactive transport simulations on unstable dissolution fronts. As phenomenon arises from inherent heterogeneity rocks, heterogenous initialization fields is needed to model such a phenomenon. While modeling fronts has been extensively studied in past, geostatistical information required initialize heterogeneous usually...

Abstract—Well logging records can help to answer many questions from a wide range of special interested information and basic petrophysical properties to formation evaluation of oil and gas reservoirs. The accurate calculations of porosity in carbonate reservoirs are the most challenging aspects of the well logging analysis. Many equations have been developed over the years based on known physi...
